Abstract
The purpose of this review was to examine the effect of video decision aids on adult patients' advance care planning-related outcomes. Seven English electronic databases (PubMed, Cochrane, MEDLINE, EMBASE, PsycINFO, CINAHL, OpenGray) and 3 Chinese databases (CNKI, WanFang, and VIP) were searched to identify relevant studies. Fourteen randomized controlled trials were included. The results of the meta-analysis showed that video decision aids reduced patients' preferences for life-prolonging care (risk ratio [RR], 0.43; 95% confidence interval [CI], 0.31-0.61; P < .01), cardiopulmonary resuscitation (RR, 0.54; 95% CI, 0.46-0.64; P < .01), and intubation tube placement (RR, 1.65; 95% CI, 1.09-2.48; P = .02) and increased patients' willingness to have a goals-of-care conversation (RR, 1.87; 95% CI, 1.32-2.65; P = .0004) and knowledge of advance care planning (RR, 0.80; 95% CI, 0.50-1.09; P < .01). However, because of the variability among the studies, the results have limitations. Future research needs to increase the sample size and improve the experimental design to confirm the impact of video decision aids on advance care planning.
